In short
- Jeju is Korea's volcanic island paradise — ~1h10 by plane from Seoul (Gimpo), and one of the world's busiest air routes. A UNESCO triple-crown site (Hallasan, lava tubes, Seongsan sunrise peak).
- Rent a car. The island is big (~73km across) and buses are slow — ~70% of visitors drive. Residents need a Korean licence; tourists need a 1949/1968 IDP + home licence (see car rental).
- 3–4 days is the sweet spot; 5+ to hike Hallasan and slow down. Best in spring (Apr–May) and autumn (Sep–Oct).
- Domestic travel needs only your ARC/ID (no passport) — but note Jeju has its own 30-day visa-free entry quirk for some direct-arrival tourists.
Koreans say visiting Jeju feels like going abroad without leaving Korea — volcanic cliffs, tangerine groves, turquoise water, and haenyeo (female free-divers). Here's how to do it well. As a resident, getting there is easy: see domestic flights & ferries.
Getting there & around
- Fly: Gimpo–Jeju is ~1h10 and cheap if booked ahead; also from Busan and other cities. Ferries exist but are long.
- Car: the way to see Jeju. Book via Klook/Trip.com, take full CDW insurance, and film a walkaround at pickup/return (Jeju has Korea's most rental disputes). Your T-money works on Jeju buses too.
- No car? Buses (incl. the 600 airport limousine to Seogwipo) and Kakao T taxis work but eat time; day tours (~₩40,000–80,000) hit the highlights. Navigate with Naver/Kakao Map — paste phone numbers as destinations.
- Where to base: Jeju City (north, airport, urban) vs Seogwipo (south, waterfalls, scenery). With a car, location matters less — anywhere is ~1h.
Don't-miss sights
- Hallasan (1,947m): Korea's highest peak. Summit trails (Seongpanak/Gwaneumsa) are 8–10h and need a QR reservation (book on the 1st of the month at visithalla.jeju.go.kr); easier options like Yeongsil (~3h) skip the booking. See hiking.
- Seongsan Ilchulbong: a dramatic tuff-cone "sunrise peak" — a short 30-min climb with huge views.
- Manjanggul Lava Tube: a world-class volcanic cave, cool even in summer.
- Beaches: Hyeopjae & Geumneung (clear, shallow), Hamdeok, Woljeongri (cafe strip).
- Udo: a mini-island 15 min by ferry from Seongsan — rent an e-bike to loop it.
- Osulloc Tea Museum & green-tea fields, waterfalls (Cheonjiyeon, Jeongbang), and the coastal Olle trails.
Eat & experience
- Black pork BBQ (흑돼지) — the island signature; plus fresh seafood and haemul ramyeon (seafood ramen) at beach shacks.
- Tangerines (감귤) everywhere — peak winter season; tangerine cafes and desserts are a whole genre.
- Haenyeo culture: watch the free-divers or visit the Haenyeo Museum — a UNESCO-recognized heritage.

Common questions
Do I need a passport to fly to Jeju?
No — domestic travel needs only your ARC/ID. Bring the physical card.
Can I skip renting a car?
You can, using buses/taxis/tours, but it's slower and limits you. Most visitors (and residents) drive.
How many days?
3–4 for highlights; 5+ to hike Hallasan and relax.
Best time to visit?
Spring (Apr–May) and autumn (Sep–Oct). Summer is hot, wet (monsoon/typhoons) and crowded; winter is quiet with tangerines and possible Hallasan snow.
